This invention relates to an atomizer of the portable pocketr type adapted particularly for use in spraying perfume or the like, and has for its object to provide a simple construction which may be easily assembled and will be positive in its action.

A further object of this invention is to provide a positive seal for closing the liquidcontaining chamber to prevent evaporation or inadvertent discharge thereof when the device is not in use.

A still further object of the invention is to provide a slidable top wall for the casing which will serve as a cover'and at the same time retain the air pumping plunger in place, the same being so arranged as to move the cover positively to open position at the time of permitting the plunger to move to operating position.

A still further object of this invention is to provide resilient means for forcing the liquid closing means into sealing position.

A still further object is to provide a runway withtabutmentsl at its ends for mounting the top wall of the casing to guide and limit its action.

`With these and other objects and advantageous features in view, the invention consists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawings, and more particularly Set forth in the appended claims.

Fig. 12 is a perspective view of the deck plate with the rockable cover mounted thereon and the closure member of the opening in the top wall mounted thereon.

In the use vof pocket atomizers, it is essential that the liquid be sealed against discharge when not in` use, even though the container be inverted as is apt to be the case when carried in the pocket or handbag of the user; it is also desirable that the air pump be wholly contained within the casing when` the device is inoperative, and in order" to obtain these results, I have provided a top wall and slidably mounted the same(A so that when in one position it maintains the plunger within the casing and the liquid chamber sealed, while when inl another position it permits operation of the plunger and uncovers the discharge openings for the atomizing means for operation; and the following is a detaileddescription of the present embodiment of this invention illustrating the preferred means by which these advantageous results may be accomplishe With reference to the drawings, 15 designates the side walls of the casing which may be drawn in tubular form if desired in any suitable shape. The e'nd portion of the wall is notched as at 16 to permit discharge therethrough of the atomizing mechanism within the casing.. A bottom wall 17 is provided which has an opening 19 therein closed by a suitable plug 20 with washer 21 thereabout, the stock of the bottom being turned inwardly to form a neck 22 to provide suicient threads for sealing purposes.

Within the casing a cylindrical tubular chamber 23 is provided communicating with the opening 19 for the reception of a liquid 24 therein, such as perfume or the like. This chamber is closed by a top 25 which has a tube 26 extending therethrough narrowed to form a discharge nozzle 27 outside of the chamber and extending a sufficient distance Within the chamber to enter the liquid even when at a low level therein. There is also rovided a vent tube 28 entering the chamer in a similar manner to that of the discharge tube 26, but terminating above the liquid level. l

A cylindrical tubular air chamber 29 is located within the casing and is closed at its bottom by the Wall 17 and at its top by a deck plate 30, presently to be described in more detail. A tube 31 extends from the bottom portion of the air chamber 29 having a discharge nozzle 32 to direct air across the end of the liquid nozzle 27 to lift and discharge the liquid'therefrom in the form of a mist or spray as is common in the atomizing action lNithin the chamber 29, there is a piston 33 having a flexible washer 34 thereon which is lifted upwardly by means of a spring 35 and forced downwardly by means of a plunger having a finger knob 36 and plunger rod 37 to force the air through the tube 31. y The deck plate 30 has an opening therein to permit reciprocation of the plunger rod 37 and is also provided with a slot or opening 38 to center or position the nozzle. 32 in aligned relation' with the nozzle 27 for atomizing action. The deck plate 30 is also provided With ears 39 having openings 40 therein to pivotally mount the closure member 41 l by means of trunnions 42. rlhe closure member is formed in somewhat the shape of an obtuse angle with its apex in line with the trunnions 42, see Figures 5 and 10, so that the same will rock about the trunnions to close the nozzle 27 and vent 28 when in one position by means of a resilient pad 43 of rubber or the like held within the closure member by any suitable means such as by folding the edges over the same. The closure member is operated by means of a sliding top Wall 44 for the casing.

The top wall is of a size to completely cover the top edges of the walls 15 when in closed position, and has flanges 45 with inturned portions 4G to slide Within the tracks or rooves 47 formed in the side wall of the casing 15. This top wall has a resilient finger 48 which engages the cover 41 and slides there-along to either side of its pivot, whereby a movement of the top wall 44 to closed position causes the finger 48 to move the closure member to close the openings of the nozzle 27 and vent 28 and hold this closure member resiliently in such closed position, and when the top wall is moved to open position, the finger 48 releases its pressure on the closure member and moves to engage portion 49 of the closure on the opposite side ofthe pivot, thereby forcing this end downvwardly and the opposite end of the closure 5 upwardly to open the nozzle 27 and vent 28 to vpermit discharge of the atomizing means,

The cover is also provided with a lip or flange 50 Which serves to close the notch 16 in the edge of the casing through which the discharge takes place. The top wall 44 is also provided with an o ening 51 which when in open position reglsters with the plunger and permits action Y thereof through this opening. When the cover is in closed position, the plunger is retained within the casing, as shown in Figure 5 by engagement with the top wall to prevent its rmovement upwardly therefrom. Itis of course understood that the plunger must be moved to a position within the casing before the top wall can be closed.

In order to close the opening 51 when the top wall is in closed position, l have mounted ,a bridge member 52, which has a finger 53 eX- tending through an opening 54 in they deck plate, and a portion 55 to surround the plunger rod 37 to retain it in place to tightly close the opening 51, preserve the finished appearance of the device and prevent entry of dirt and foreign matter to the Working parts of the casing when the same is in closed position in the pocket of the user.

' While l have described certain construction forms which embody the principles of my invention, it is obvious that other desired changes in arrangement may be made within the spirit and the scope of the invention as defined in the appended claims.
